There's been a lot of work done over the last couple of weeks, but it's mostly major structural stuff that's probably not all that interesting for Arduino people. It's getting close to the good stuff now though.
The electrical roughing-in has been done, and the workshop / garage now contains about 400m of power / lighting cable and 600m of data cable. Because the house is being automated (using a lot of Arduino bits embedded around the place) the cabling has all been brought back to a central wiring cabinet. Typically electrical wiring is done by running power to a light switch in the wall, and from there to the light fitting. I've had all the light fittings etc wired directly back to the cabinet so they can be connected to automation control modules. Anywhere that a light switch would be mounted on the wall has Cat-5 cable running to it where there will be a control surface, perhaps an Arduino-powered physical switch (like the one I did in the bathroom: http://jon.oxer.com.au/blog/id/307
) or perhaps something like an Android tablet fitted into the wall.
The wiring cabinet currently looks like this:
As you can see it has a back fitted to it (floor sheeting) to give it a strong surface for mounting a couple of switchboards and a small rack cabinet. It's located on the centerline of the house with easy access both top and bottom so cabling can run in from either direction. Inside the ceiling I've mounted 19mm floor sheeting with carpet tiles on it so that crawling around dragging cable is actually quite comfortable.
There are 35 Cat-6 drops (the big grey bundle) and 15 Cat-5e drops (yellow) in that picture. I'm using Cat-6 for wall mounted network jacks that computers will plug into, and Cat-5e for fixed automation devices mounted in the building such as Freetronics "Eleven" boards (http://www.freetronics.com/eleven
) inside the ceiling space with temp / humidity sensors, IP cameras, security sensors, etc. The single blue Cat-5e you can see is to connect to an electric curtain controller from Elegine (http://www.elegine.com
) with a TCP/IP interface so I'll be able to use Arduino-based sensors to control the curtains. There will be about another 8 of those going in over the next couple of weeks.
This weekend I stuffed the ceiling insulation in place ready for plasterboard ("drywall" for you yanks) so tomorrow will be a big day. It'll suddenly go from an exposed frame to feeling like a nearly-completed room:
A previous update showed a regular frame over the double door. I've since knocked out the studs over the door and replaced them with floor sheeting mounted flush with the close side of the frame. I'm intending to mount a pair of 22" LCDs over the door facing into the workshop / office area, recessed into the wall so the faces are close to flush with the plasterboard on the office side.
The workstations have been cabled up using almost the plan I posted previously:
Two sets of 4-way outlets over the bench, one set below. One double-outlet LAN plate over the bench, one below. If you compare reality with my original plan you'll see there's a blank space where I intended to put in ducted-vacuum fittings for fume extraction. I'll still do that, but not in the wall. It turned out to be a pain to put the fittings through the wall so I'm going to mount the vac fitting on the bench surface itself, with the pipes running along under the bench tight up underneath.
